Xiaomi Mi Band 4 arrives with an interesting novelty

Sure, the display will be colorful, but the biggest bang may not be this, it’s a new central unit!

The fact that Xiaomi is introducing a new central tile in the smart bracelet has several projections. Most importantly, perhaps, that A unit called Huangshang No.1 is not the usual ARM-based solution, but an open source RISC-V-based processor. Currently, ARM solutions are almost dominant in the market for both mobile phones and wearable smart devices, but it increasingly looks like hegemony is coming to an end soon. The proliferation of RISC-V systems is also likely due to Qualcomm’s significant investment in SiFive, one of the largest manufacturers of RISC-V-based processors.

The move, that is, the neglect of ARM technology, is understandable even when we think of Huawei’s sanctions in the recent past. Although ARM is not a U.S. company, it has entered the boycott, saying they also use U.S. technologies in their products, and because they are subject to an embargo on their own products, their developments will also be withdrawn from Huawei. As is well known, the redesigned cores of ARM work in Huawei’s core chips, so Huawei is shot not only from the software side (Google) but also from the hardware side (ARM).

Going beyond the business, strategic aspects of the thing, it is important to note that a Huangshang No.1 is a more efficient solution than the ARM Cortex M4, so that's why the switch is understandable. THE Huangshang No.1 the world's first wearable processor with an integrated AI neural network. It features four basic artificial intelligence engines, a heart biometrics, an ECG, an ECG Pro, and an arrhythmia disorder monitoring engine. The point is that the new Mi Band is also expected to get a significantly expanded set of services behind the color display, which can be seen by competitors!
